Stephen Kelly 60a981ea8e Features: Enable compiler extensions by default.
Compilers enable their extensions by default, and disabling them
implicitly can lead to results which are surprising or non-obvious
to debug.

 (Compiler feature extensions by default, 29 May 2014)
2014-05-31 12:16:12 +02:00
Stephen Kelly dd043c3f21 Features: Add support for C++14 features.
Record the features implemented by GNU 4.9 and Clang 3.4.

Stephen Kelly 0dfe395e3c Features: Add COMPILE_FEATURES generator expression.
Allow setting build properties based on the features available
for a target.  The availability of features is determined at
generate-time by evaluating the link implementation.

Ensure that the <LANG>_STANDARD determined while evaluating
COMPILE_FEATURES in the link implementation is not lower than that
provided by the INTERFACE of the link implementation.  This is
similar to handling of transitive properties such as
POSITION_INDEPENDENT_CODE.

Brad King 5d12b87b9d cmGeneratorTarget: Improve GetCreateRuleVariable API
Pass the language and configuration to the method so it can return the
complete rule variable name.

Stephen Kelly e0890d03a4 Features: Extend concept to C language.
Add properties and variables corresponding to CXX equivalents.

Add features for c_function_prototypes (C90), c_restrict (C99),
c_variadic_macros (C99) and c_static_assert (C11). This feature
set can be extended later.

Add a <PREFIX>_RESTRICT symbol define to WriteCompilerDetectionHeader
to conditionally represent the c_restrict feature.

Mikołaj Siedlarek 1bed75a590 OS X: Use -iframework for system framework directories
Just like -I flag has its -isystem counterpart which marks an include
directory as a system directory and prevents unwanted warnings, on Apple
systems there is -iframework -- a system directory replacement for -F.
Use this flag to implement include_directories(SYSTEM) for frameworks.

Stephen Kelly 205215fb8a cmTarget: Add CXX_STANDARD_REQUIRED to control decay. 2014-05-07 12:17:49 +02:00
Stephen Kelly 1df2116bfa Features: Decay language flag if requested is not available.
Use the highest standard compile flags available if requested language
version is too new.

This supports use-cases like

 set(CMAKE_CXX_STANDARD 14)

 # Compiled with -std=c++11 with GNU 4.7, which has no -std=c++14
 # or equivalent flag
 add_executable(main main.cpp)

This can be used in combination with preprocessor defines which
communicate the availability of certain language features for
optional use.

Stephen Kelly 5412deded1 cmTarget: Transitively evaluate compiler features.
Extend the interface of the target_compile_features command with
PUBLIC and INTERFACE keywords. Populate the INTERFACE_COMPILER_FEATURES
target property if they are set. Consume the INTERFACE_COMPILER_FEATURES
target property from linked dependent targets to determine the final
required compiler features and the compile flag, if needed.

Use the same pattern of origin-debugging which is used for other
build properties.

after evaluation.

Stephen Kelly 03355d6b5b cmTarget: Add COMPILE_FEATURES target property.
Use the contents of it to upgrade the CXX_STANDARD target property,

compile flag or other language specification on GNU when that is
needed for the feature.

Stephen Kelly e6971df6ab cmTarget: Make the source files depend on the config.
Disallow the use of config-specific source files with
the Visual Studio and Xcode generators. They don't have
any way to represent the condition currently.

Use the same common-config API in cmQtAutoGenerators. While
it accepts config-specific files, it doesn't have to support
multiple configurations yet.

Loop over the configs in cmTargetTraceDependencies
and cmGlobalGenerator::WriteSummary and consume all source
files.

Loop over the configs in cmComputeTargetDepends and compute the
object library dependencies for each config.

Ben Boeckel 270eb96df0 strings: Remove cmStdString references
Casts from std::string -> cmStdString were high on the list of things
taking up time. Avoid such implicit casts across function calls by just
using std::string everywhere.

The comment that the symbol name is too long is no longer relevant since
modern debuggers alias the templates anyways and the size is a
non-issue since the underlying methods are generated since it's
inherited.

Brad King fba51b096e MSVC: Add properties to configure compiler PDB files (#14762)
Since commit v2.8.12~437^2~2 (VS: Separate compiler and linker PDB files
2013-04-05) we no longer set /Fd with the PDB_NAME or PDB_OUTPUT_DIRECTORY
properties.  Those properties now exclusively handle linker PDB files.
Since STATIC libraries do not link their compiler PDB file becomes more
important.  Add new target properties "COMPILE_PDB_NAME[_<CONFIG>]" and
"COMPILE_PDB_OUTPUT_DIRECTORY[_<CONFIG>]" to specify the compiler PDB
file location and pass the value to the MSVC /Fd option.

Brad King d2059d2511 cmVersion: Fix CMake_VERSION_ENCODE for date in patch level
Use a uint64_t to store encoded version numbers so we have plenty of
bits available.  Encode with room for up to 1000 minor releases between
major releases and to encode dates until the year 10000 in the patch
level.  This is necessary because CMake development versions prior to
release 2.8.0 used the date in the patch level, and this practice may be
restored after the 3.0 release.

Rolf Eike Beer c768e398f9 cmMakefile: make some methods take const std::string& instead of const char*
Most callers already have a std::string, on which they called c_str() to pass it
into these methods, which internally converted it back to std::string. Pass a
std::string directly to these methods now, avoiding all these conversions.
Those methods that only pass in a const char* will get the conversion to
std::string now only once.
